Modern Software Needs Embedded Modern C++ Programming
summary
Argument: embedded systems deserve Modern C++ but must match compiler constraints, so migration splits into three Ages that map features to available toolchains. Practical steps include switching .c to .cpp, fixing cast errors, using brace initialization, static_assert, constexpr, and unique_ptr/std::array/move semantics for predictable, zero‑overhead lifetimes. Avoid heap and exceptions on hard real‑time paths; use fixed pools or flat containers. SG14 prototypes deterministic exceptions, a memory management facility, flat_map and ring buffers; companies like Sonova and Adaptive AUTOSAR already move toward C++17/20.
